Finding any new fossil is rare. Finding invertebrate fossils is made even more rare because of the squishy nature of most invertebrates. Sometimes the wandering paleontologist, toiling away with utmost care through dust and debris, can find parts of squishy invertebrates like scolodonts (polychaete jaws), coral rubble, carbonate shell cement, or maybe sea star or . . . → Read More: Yicaris – Progenitor of the Crustacea

This decay bias makes it much more difficult to distinguish them from their ancestors . . . → Read More: Rotting Lamprey Implications

Gutierrez-Marco and colleagues discovered a quarry replete with marine invertebrate fossil, including potentially some of the largest trilobite specimens ever found. Curiously though, these capricious little critters were found exhibiting some rather gregarious behavior! They . . . → Read More: Trilobites Ride the Crazy Train
